Spark MINI is capable of working in an environment between 32°F~127.4°F / 0°~53° C. If Spark MINI reaches the limit of the temperature range, the status indicators will start to show red colors and blink quickly to warn it is close to temperature limitation.
If the situation is not improved, Spark MINI will be shut down temporarily, and it will be able to turn on when the temperature is back to normal again.
If you encounter the temperature warning without finding the device to be heating at all, please submit a support ticket and provide the details for your usage (speaker volume, playtime).
